I have been researching this for years for various swaps all the back since the infancy of CA smog legal swaps from companies that pioneered this like Jags that Run. Note I said smog legal swaps not just engine swaps which are obviously as old as cars.
Couple important points here, the swap not only has to be from the same year or newer vehicle but it also has to be the same type for example passenger car to passenger car or light duty truck to light duty truck etc. Also, since these drivetrains and systems are certified as complete assemblies that would be from the air box to the cats which obviously creates problems trying to fit a modern 1500 or Tahoe LS airbox assembly into an OBS engine bay. Not saying it can't be done but I've yet to see one. You then have to get your install certified by a smog referee. The other option is the E-rod which someone posted. The cheapest I have seen an LS3 e-rod is $9,100. The LT1 and LT4 are obviously much more.
I know of someone who owned a shop that was doing the "gray area" smog checks that everyone seems to think is the way to go. Carb has investigators that do spot checks and if they find a violator they will often flip the shop and then all the customers who think they're being slick. The test should be whether the tailpipe is clean but that's not the way they view it.
And for those of you in other states who think California and these other places with restrictive laws are their problem guess what, you are all soon to be next via the EPA and the Feds. If you follow SEMA and their action network the regulatory agencies believe they can prohibit you from converting your own personally owned car into a race vehicle. That is just the beginning of what they have planned for gas engines.
You really think they're gonna keep beating that horse now that the greenies are ramming electric everything down everyone's throats?
